👉 Isophotes, in geometry, are two lines that intersect at a right angle. They are named after their shape and are often used to represent lines with equal lengths or angles. Isophotes can be classified into two types based on whether they form an isosceles triangle (a triangle where all three sides have the same length) or not. Isophotes are also known as half-lines in Euclidean geometry, which means that they do not intersect at a single point, but rather
